Will we get the all the patron features listed in PHP at full release? Misty escape looks especially strong. I wonder if Misty escape will proc in game if you have temporary hit points from say armor of agathys? Does the damage have to hit your actual hp or can you still misty escape away if you have temporary hit points? I ask because I notice sometimes hellish rebuke doesn't give me my reaction if i have temp hp. I don't know if this is a bug, but I wonder if misty escape will have the same issue, as it is the main reason I want to play this sub-class. This is what the PHP says about the Archfey up until the last patron feature we will have access to in 1.0:
Fey Presence
Starting at 1st level, your patron bestows upon you the ability to project the beguiling and fearsome presence of the fey. As an action, you can cause each creature in a 10-foot cube originating from you to make a Wisdom saving throw against your warlock spell save DC. The creatures that fail their saving throws are all charmed or frightened by you (your choice) until the end of your next turn.
Once you use this feature, you can't use it again until you finish a short or long rest.
Misty Escape
Starting at 6th level, you can vanish in a puff of mist in response to harm. When you take damage, you can use your reaction to turn invisible and teleport up to 60 feet to an unoccupied space you can see. You remain invisible until the start of your next turn or until you attack or cast a spell.
Once you use this feature, you can't use it again until you finish a short or long rest.
Beguiling Defenses
Beginning at 10th level, your patron teaches you how to turn the mind-affecting magic of your enemies against them. You are immune to being charmed, and when another creature attempts to charm you, you can use your reaction to attempt to turn the charm back on that creature. The creature must succeed on a Wisdom saving throw against your warlock spell save DC or be charmed by you for 1 minute or until the creature takes any damage.
